Chapter 4 Configuring Gigabit Ethernet Interfaces
Enabling the Interface
When you configure an interface speed and duplex mode, follow these guidelines:
• If both ends of the line support autonegotiation, use the default autonegotiation settings.
• When autonegotiation is turned on for either speed or duplex mode, it autonegotiates both speed and
the duplex mode.
• If one interface supports autonegotiation, and the interface at the other end does not, configure the
duplex mode and speed on both interfaces. If you use the autonegotiation setting on the supported
side, the duplex mode setting is set at half-duplex.
Note In the following procedure, press the Return key after each step unless otherwise noted. At any
time, you can exit the privileged level and return to the user level by entering disable at the
Router# prompt.
To configure speed and duplex operation, follow these steps while in interface configuration mode:
Enabling the Interface
Note In the following procedure, press the Return key after each step unless otherwise noted. At any time,
you can exit the privileged level and return to the user level by entering disable at the Router# prompt.
Command Purpose
Step 1
duplex [auto | half | full]
Example:
Router(config-if)# duplex auto
Specify the duplex operation.
Step 2
speed [auto | 1000 | 100]
Example:
Router(config-if)# speed auto
Specify the speed.
Command Purpose
Step 1
interface gigabitethernet slot/port
Example:
Router(config)# interface
gigabitethernet 0/1
Specify the port adapter type and the location of the interface to be
configured. The slot is always 0 and the port is the number of the port.
Step 2
no shutdown
Enable the gigabit Ethernet interface using the no shutdown command.
